Integrates spatial texture and contextual information to map the spatial extent of an urban area (i.e. HBASE) using Landsat imagery, which is then used as an input to impervious surface mapping (GMIS below). Details.

Multiple classes of settlement based on combination of population density, population size, and density of built-up areas

Uses GHS-BUILT built up density and GHS-POP population grid as inputs to create classes (urban center, urban cluster, and rural) derived from combinations of population density, size, and density of built-up. Details.
